HAY-PRESS.

To all whom it may concern:

Be it known that I, MARION D. GUTHRIE, a citizen of the United States, residing at Hous ton, in the county of Harris and State of Texas, have invented new and useful Improvements in Hay-Presses, of which the folowing is a specification.

This invention relatesto a hay or other press of that type in which two compression strokes are imparted to the plunger by one continuous rotation of the sweep.

to the plunger through an oscillating frame I or triangle arranged in the path of the cams.

With these ob ects in view and others, as will appear as the description proceeds, the invention comprises the-various novel features of construction andarrangement of .parts which will be more fully described hereinafter and set forth withpartioularity in the claims appended hereto.

In the accompanying drawing, which illustrates one of the embodiments of the invention, Figure 1 is a plan view of the hay press with intermediate portions broken away. Fig. 2 is a side elevation thereof. Fig. 3 is a bottom plan view of the cam-carrying member or cross piece. Fig, 4 is a side view thereof.

Similar reference characters are employed to designate corresponding parts throughout the several views.

Referring to the drawing, A desi nates the bed or base frame of the press which is of any approved construction and is provided at one en with a compressing chamber B of any approved form in which reciprocates a lunger C. At the end of the frame or bed opposite from the compressing chamber is pivoted a sweep D, the pivot 1 thereof passing through the sweep and cross-beam 2 of the frame. Disposed between the sweep and cross piece 2 is a horizontal member 3 rigidly Specification of Letters Patent.

These cams areformed by undercutting theiends of the member 3," as shown and they are adapted to alternately operate on the mechanism cennected with the plunger to impart two strokes to the latter by one rotation of the sweep. The usual lead pole 7 is employed that is bolted or otherwise socured to the sweep and the braces 4.

The plunger C is hingedly connected with a rod 8 which, in turn, is hingedly connected with a triangular frame or element 9. This element is mounted for oscillation on a vertical pivot 10 mounted on the bed A adjacent the 'rear endthereof and constitutes a bell crank lever. The element 9 is in the form of a right angle triangle and the plunger rod Sis connected with one of its acute angles, while the other acute angle or corner is disposed in the path of the cams 5 so as to receive movement by the cams wiping on the same, the pivot 10 being located at the ri ht angular corner of the element 9. adapted to be oscillated in one direction so as" to move the plunger on its compression stroke and after the cam 5 disengages from The e ement 9 is theelement, the latter, together with the a metal cap 12 so as to receive the wear.

By undercutting the ends of the member 3, horizontal terminal fianges' are formed which are adapted to extend over the rear 9 extremity of the arm of the bell crank lever 9 and hold the latter down against the base frame or bed'when the lever is tilted by the cam so as to thereby prevent too great a strain on the pivot 10. In other words, the element 9 is maintained in a horizontal plane during its movement not only by the pivot 10 but by the terminal flanges on the member 3 engaging over the rear end of the said element.

In practice, the compressing chamber is supplied with hay or other material to be compressed and the sweep D is rotated in any suitable manner, as for instance, by horse power, and one rotation of the sweep causes the element 9 to be oscillated to re c'iprocate the plunger twice, thus enabling a double charge of hay to be com ressed. The construction of the press is simp e, dura- 5 bio and comparatively inexpensive and the parts are so proportioned as to obtain an increased leverage, so that a powerful compression of the materials is obtainable.

I have described the principle of opera.- tion of the invention, together with the apparatus which I now consider to be the best embodiment thereof, but I desire to have it understood that the apparatus shown is ward end thereof, a plunger movable in the chamber, a rod pivotally connected with the. plun er, a sweep pivoted on the frame, a

.mem er rigidly connected with the sweep and formed at its ends into cams, and horizontal 25 terminalflanges projecting beyond the cams, an oscillatory element pivotally mounted on the frame between the chamber and sweep and having a portion arrangedin the path of the cams and over which the saidflanges 0 move, a hinge connecting the plunger rod' with the element, and means connected with the element for returning the same and the parts attached thereto to normal position.

In testimony whereof, I aflix my signa- 5- ture in presence of two witnesses.
